Events

Craft has all kinds of events you can use to customize how things work. See Using Events in a Custom Module (opens new window) for an example of how to wire up event code using a module.

# Saving Entries

While every element in Craft CMS has a common set of events your custom code can subscribe to, the entry-saving workflow is one of the most common and complex.

See Handling Entry Saves (opens new window) for more on entry-specific concepts.

Generally, entries progress through the following order of operations:

  1. Pre-flight checks that trigger EVENT_BEFORE_SAVE.
  2. Validation that triggers EVENT_BEFORE_VALIDATE and EVENT_AFTER_VALIDATE.
  3. Saving for the initial site that triggers EVENT_AFTER_SAVE.
  4. Propagating non-translatable changes to the entry’s other sites, which repeats steps 1-3 for each site before triggering EVENT_AFTER_PROPAGATE.
